SPECIFICATION forming part of Letters Patent No. 389,407, datedSeptember 11, 1888.

Serial N0.2l0,600. (No model.)

To all whom it may concern:

Be it known that I, ALVA L. Prcirn'rrfresiding at New Haven, in thecounty of New Haven and State ofOonnecticut, have invented certain newand useful Improvements in Machines for Making Paper Boxes; and I dodeclare the following to be a full, clear, and exact description of thesame, reference being had to the accompanying drawings,which form a partof this specification.

My invention relates to an improvement in machines for making paperboxes, the object being to produce a machine which shall be compact,efficient, and have a large capacity for work and for drying boxes.

\Vith these ends in view my invention consists in a machine havingcertain details of construction and combinations of parts, as will behereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is aview in front elevation of amachine embodying my invention with the front of the casing inclosingthe reciprocating heads removed. Fig. 2 is aplan view of the machinewith portions broken away to show its operatingconnections. Fig. 3 isabroken sectional view of the machine on the line a a of the precedingfigure, looking in the direction of the arrows Z) I). Fig. 4 is asectional view on the line c of the same figure and looking in the samedirection. Fig. 5 is a similar view on the line (I d of the same figureand looking in the direction of the arrows c e, the gumfonnt beingremoved. Fig. 6 is a similar view on the line ff of the same figure andlooking in the direction of the arrows last mentioned. Fig. 7isadetached View, partly in section and partly in elevation, and showingthe gum-fount and its operatingconnections. Fig. 8 is a similar Viewshowing the gummers and their operating-connections, and taken on theline 7t 7a of Fig. 1, and looking rearward toward the gummers in thedirection of the arrows Z Z of that figure. Fig. 9 is a detached planview of the feed regulator. Fig. 10 is a similarview thereof in verticalsection on the line i i of Fig. 9, and looking in the direction of thearrowsj j on such figure. Fig. ll is a broken plan view showing thescoring and cutting table and the folding-die. Fig. 12 is a view invertical longitudinal section on the liner; 7 of theprecedspring-actuated pawl in broken lines. Fig. 18 is a reverse planview of the gear. Fig. 19 is a detached plan view of the ratchet. Fig.

20 is a plan view of a blank. Fig. 2i is a perspective view of a box asmade by the machine, and Fig. 22 is a detached enlarged plan view of thecage and the operatirig-connections of the shaft carrying the followers.

Thestock, A, from which the boxes are made is prepared in a long stripof suitable width and wound in a coil upon a sleeve, B, mounted upon amovable spindle, 0, having one end supported in the frame D of themachine and the other end in a shaft, E, of which one end is supportedin ahauger, F, and the other end in the frame of the machine, that endof the sleeve adjacent to the shaft being provided with faceratchet-teeth G, which are engaged by a spring-actuated dog, H, locatedinthe adjacent end of the shaft, (see Fig. 10,)whereby thesleeve iscoupled with the shaft, so as to be rotated thereby. A cone-pulley, I,mounted upon the said shaft with its smaller end forward, is connectedby a belt, J,with a similar pulley, K, reversed in position and carriedupon a shaft, L, supported at its forward end in a horizontal arm, M,attached to the hanger F, and at its rear end in a hanger, H, beyondwhich it projects to receive the pulley N, con nected by a belt, 0, witha pulley, P, secured to a short shaft, Q. mounted in the frame of themachine, and provided at its forward end with a pinion, R, meshing witha worm, S, located upon the shaft T, extending the length of the machineand supported under the bed plate U thereofin bearings Vand W, as shownin Fig. 2 of the drawings.

The uniform feeding of the stock is regu- IOO lated and controlled bythe coil itself through a roller, X, resting upon it and descending bygravity as it is reduced in diameter, and mounted in an arm, Y, theopposite end of which is secured to a triangular frame, Z, supported andguided in vertical reciprocation by a frame, A, the legs B B of whichhave hearing in blocks G O, secured to the horizontal arm M, beforementioned. The outer face of the longer and inclined side of the saidtriangular frame engages with an anti-friction roller, D, mounted at theouter end of an arm, E, offsetting from a horizontal slide, F, passingthrough the arm M, supported by a frame, G, and an arm, H, respectivelysecured to the front and rear faces of the said arm M, and connected atits inner end with a shipper, I, controlling the position of the belt Jupon the conesIand K. As the coil of stock is gradually unwound andreduced in diameter, the roller X and the angular frame Z descend, thelatter through its inclined side drawing the slide forward and bringingthe belt toward the smaller end of the driven cone I and toward thelarger end of the driving-cone K, whereby the rate of rotation isincreased in the former, the parts being'constructed and arranged sothat the contraction of the coil will always be exactly met by aproportional increasein the rapidity of its rotation, wherefore thestock is at all times fed uniformly to the machine. From the coil thestrip passes upward and between two guide-rolls, J J, and from thence toa reciprocating table, K, located between guides L L, secured to thebed-plate U, and provided at-its forward end and upon its opposite edgeswith frames M M, each carrying upon their inner faces a pair ofspring-actuated jaws, N N, having the forward ends of their adjacentedges provided with teeth out on aforward slant, pivoted to the rear oftheir longitudinal centers, and having a spring interposed between theirrespective rear ends or tails, whereby they are adapted to seize thestrip as the table is advanced and to slip over it as the same isretracted, the table being reciprocated by a lever, O, fulcrumed to theunder face of the bed-plate U and actuated by thecam 1? upon the shaftT, before mentioned. Thejaws N N, seizing the strip, carry it forward tothe table Q, provided upon its upper face with two parallelknife-incisions, R R, tapering at each end, and with four intersectingscoring-incisions, S S, located in advance of the knife-incisions.Screws T T, mounted in the bed-plate U and located under the table, areprovided for vertically adjusting it as the thickness of the paper orother conditions may demand. Four guides, U, arranged in pairs,respectively, extending over the opposite edges of the table, serve toguide the strip and keep it in place thereupon.

Two tapering cutting-knives, V V., corresponding in shape to theincisions R R, and hence adapted to cut a double-V-shaped piece out ofthe strip near each edge, and four scorers, W, arranged to correspond tothe scoring-incisionsj S,are secured to the lower face of a plate, X,located upon the lower end of a skeleton head, Y, mounted in a casing,Z, having a removable front, A and vertically reeiprocated in suchcasing through a block, B, mounted for horizontal reciprocation in thehead and provided with a central aperture, 0', receiving an eccentric, Dformed upon the forward endof the main drivingshaft E which latter ismounted in the frame F and provided with adrivingpulley, G, andconnected through gears H and l", shaft J, and gears K L and M with theshaft T, which it drives.

The cutting-off knife M is also secured to the plate X and at a point inadvance of the scorers, and operates in conjunction with a cuttingedge,N", formed at a corresponding point in the table Q, already described,to cut the strip into blanks like that shown by Fig. 20 of the drawings,each blank being virtually divided by the removal of the V-shaped piecesand the seoringlines into the bottom portion, 0 the end portions, P P,the side portions,Q Q, and the corners R R ER", all as shown. Theblanks, it will be noted, are cut on a line exactly dividing thedouble-V-shaped openings formed by the knives V V before the end of thestrip reaches the cutting-off knife. The folding-die S is located inadvance of and with one end set'against such cuttingedge N and isprovided with elevated corners T T T T, with elevated sides U" U, andwith depressed ends V V, being also adapted in depth to contain three.boxes at one time. The folding-punch W", cooperating with said die, issecured through an opening, X in the plate X to the lower end of a head,Y located in 'front of the head Y and in the same casing,

and vertically reciprocated through a block, Z", mounted in it forhorizontal reciprocation, and provided with a central circular aperture,A, receiving an eccentric, B, having a segmental series of holes, 0,receiving a screw, D securing it to the eccentric D and entering ascrew-hole, E therein, and a hole, F receiving a pin, G, projecting fromthe eccentric D and relieving the screw D from strain, the saideccentrics being proportioned so that the head Y will have about twicethe throw of the head Y as it has to enter the die and rise above it togive clearance to the incoming strip, and the segmental series of holesbeing provided for shifting the screw, and hence the relations of thetwo eccentrics, as may be required in timing the machine.

Simultaneously with the cutting and scoring of the strip the endportions of two adjacent and still undivided blanks are gummed bygummers H, operating between the knives V V and upon the table Q, andarranged in two groups of three gummers each at the opposite ends of anarm, I, secured to the lower and free end of an angular frame, J havingits upper end rigidly secured to the lower end of an upright spindle, Kconnected at such end with a bent arm, L (see Fig-8,) extending rear-ITO wardly through the head Y and attached to the head Y, which raisesand lowers it, and with it the spindle, which is mounted in abox, Msecured to the casing Z, and provided with a cam-slot, N composed of astraight lower portion, 0 and a curved upper portion, 1", and receivinga stud, Q, projecting from the spindle and operating through such studto rotate the spindle as the same is raised and lowered by the head Y,whereby the gum mers are swung forward, and then let down in a straightline or vertically between the knives V V and onto the strip, and thenlifted above the knives and swung back into a position of retirement.

The gummers are charged for each gumming of the strip from a shallowgum-distributer, R supplied from a gum-fount, S, supported upon astandard, T the said standard and distributer being formed integral andlocated upon the upper end of a short upright shaft, U, mounted in abearing, V, hung from the bed-plate U, and connected at its lower endwith a lever, fulcrumed in a hanger, X and actuated by a cam, Y mountedupon the shaft T and timed to lift the shaft U and hence thedistributer, and so immerse the gummers in the same, the gummers beinglocated, when retired, directly over such distributer. A small dischargeopening, 1 formed in the extreme lower edge of the fount, discharges guminto the distributer, and so long as this opening is open the mucilagewill flow out from the fonnt into the distributer. As soon, however, asthe gum in the distributer rises above the level of the top of the saiddischargc opening, the gum will stop flowing from the fount, and thecolumn of gum therein will be held back by the pressure of theatmosphere upon the gumin the distributer; but when the gum in thedistributer is low ered in charging the gnmmers below the level of thedischarge-opening in the fount the gum will begin to run out into thedistributer and be discharged thereinto until the opening is againclosed, as described. The gum is therefore automatically supplied to thedistributer and exactly according to the demand upon the same, and thegum ming apparatus, so far as the fount and distributer are concerned,needs no other attention than the refilling of the font.

The boxes, folded and gummed, are delivered from the folding-die into avertical rotary skeleton dryingcage composed, as herein shown, of fourvertical series or tiers of boxholding frames, Z, secured with a spacebetween each to the respective sides of a hollow square body, A,provided at its upper and lower ends with beads l3", furnished withshort shafts C, the shaft of the lower head being mounted in the part D"of the frame of the machine and that of the upper head in the bed-plateUof the machine. A ratchet,

having four teeth, is rigidly secured to the shaft of the upper head,upon which it rests, and is engaged by a pawl, 1*, actuated by a spring,G2 and located in a recess, 11*, formed in the under face of a gear, 1',adapted to fit over and inclose the ratchet, and provided upon itsperiphery with teeth engaged by a toothed rocking lever, J, fulcrumed tothe under face of the bed'plate U, and having its opposite end connectedwith a slide, K. connected with the upper end'of an arm, M, (see Fig.4,) having eccentric connection with the shaft T, and pivoted at itslower end to a hanger, N", as shown. Under these connections the cage isrotated a quarterturn for each rotation of the shaft T.

The boxes are pushed downward from frame to frame through the respectivetiers of frames and finally discharged from the cage by means of avertical series or tier of followers, 0, corresponding in number to thewhole number of frames in any one tier of frames and mounted upon ashaft, P, upon which they are separated each from the other by collarsQ", of sufficient width to bring the followers into alignment with thespaces between the frames. Horizontal arms U" U, respectively located atthe upper and lower ends of the said tier of followers, are rigidlysecured to the shaft P thereof and to a shaft, S", adapted to be rotatedand vertically reciprocated, the upper end of the said shaft S havingbearing in the bed of the machine and its lower end in the step T* ofthe machine. Acollar or plate, J arranged to turn freely on the saidshaft S, is located directly under the upper arm U, against whichitlifts. This plate is provided with a horizontal stud, 'V, forming theupper pivotal point of a link, NV, the lower end of which is connectedwith a lever, X, fulcru med to a hanger, Y, and provided at its rear endwith a roller, Z*, engaged by a cam, A mounted upon the shaft T andoperating to lift the shaft S, and hence the tier of followers, througha space measured by the distance between two adjacent box-holdingframes. The said shaft S is rotated to swing the followers into and awayfrom the cage through a pin, 13 located between and secured to two arms,R 11*, rigidly secured to the shaft S below the lower end of the link Wand playing in an elongated slot, 0 formed in the forward end of aslotted slide, D, movably secured to the lower end of the hanger Y, andpivotally attached at its rear end to the swinging lever E, hung fromthe bed-plate U, and carrying a roller, F engaged by a cam, G mounted onthe shaft T, and operating to advance and retract the slide D whichrotates the shaft 8* so as to swing the tier of followers into and awayfrom the cage.

Having described my improved machine in detail, I will now set forth themethod of its operation.

Let it be assumed that the machine is prop erly timed and that a box hasjust been produced, leaving the end of the strip cut, scored, and gummedupon the table Q. The reciprocating table K new advances and through thejaws N N moves the strip forward and its cut, gunnned, and scoredportion over the foldng-die and under the folding-punch. The knives V V,the scorers W, and the gummers I-I now descend to cut, score, and gumthat portion of the die newly brought under them, and at the same timethe cutting-ofi' first lift the corner portions, R of the blank,

after which the sides U of the die lift up the sides Q of the blank,while the depressed ends V of the die act last in lifting the gummedends P oft-he blank, such portions being folded against the cornerportions, R, of the blank, as shown by Fig. 21 of the drawings. Theknives,scorers, gummers, the cutting-off knife, and the punch now retireand give clearance to the strip, which is again advanced and theoperations detailed above are repeated. When three boxes haveaccumulated in the die and when the fourth box is formed, the lower boxwill be discharged into the uppermost boxholding frame of that tier offramesin the cage which is below the die at the time. The cage is thenrotated to bring the next tier under the die, and when the upper frameof that tier has received a box the cage is again rotated, and so on. Atevery rotation of the cage the followers are swung into the tieradjacent to them, with the respective followers above the boxes in theframes to which they correspond. The followers are now depressed, movingthe boxes each down one frame, when they swing out and permit the cageto turn again. It will thus be seen that for every revolution 'of thecage the boxes carried in the frames of its respective tiers are moveddownward each to the frame below until they reach the bottom frame ofthe tier, from which they are discharged perfectly dry, and henceretaining their shape.

I would have it understood that I do not limit myself to the exactconstruction herein shown and described, but hold myself at liberty tomake such changes and alterations as fairly fall within the spirit andscope of my invention.

Having fully described my invention,what I claim as new, and desire tosecure by Letters Patent, is-- 1.
